Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.

Nomenclature[edit]
Because it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. In colloquial usage, the names sodium bicarbonate and bicarbonate of soda are often truncated; forms such as sodium bicarb, bicarb soda, bicarbonate, and bicarb are common. The word saleratus, from Latinsal æratus meaning 'aerated salt', was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate. It is known as one of the E number food additives E500.
The prefix bi in bicarbonate comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO3) per sodium in sodium bicarbonate (NaHCO3) as there is in sodium carbonate (Na2CO3). The modern chemical formulas of these compounds express their precise chemical compositions (which were unknown when the names sodium carbonate and sodium bicarbonate were coined) and show the same ratio the other way around: there is half as much sodium per carbonate in NaHCO3 as in Na2CO3 (disodium carbonate).
Uses[edit]
Cooking[edit]
In cooking, baking soda is primarily used in baking as a leavening agent. When it reacts with acid, carbon dioxide is released, which causes expansion of the batter and forms the characteristic texture and grain in pancakes, cakes, quick breads, soda bread, and other baked and fried foods. Acidic compounds that induce this reaction include phosphates, cream of tartar, lemon juice, yogurt, buttermilk, cocoa, and vinegar. Baking soda may be used together with sourdough, which is acidic, making a lighter product with a less acidic taste.[9]
Heat can also by itself cause sodium bicarbonate to act as a raising agent in baking because of thermal decomposition, releasing carbon dioxide. When used this way on its own, without the presence of an acidic component (whether in the batter or by the use of a baking powder containing acid), only half the available CO2 is released. Additionally, in the absence of acid, thermal decomposition of sodium bicarbonate also produces sodium carbonate, which is strongly alkaline and gives the baked product a bitter, 'soapy' taste and a yellow color. To avoid an over-acidic taste from added acid, nonacid ingredients such as whole milk or Dutch-processedcocoa are often added to baked foods.[10]
Carbon dioxide production from exposure to heat starts at temperatures above 80 °C (180 °F).[11]
- 2 NaHCO3 → Na2CO3 + H2O + CO2
Since the reaction occurs slowly at room temperature, mixtures (cake batter, etc.) can be allowed to stand without rising until they are heated in the oven.
Sodium bicarbonate was sometimes used in cooking green vegetables, as it gives them a bright green colour—which has been described as artificial-looking—due to its reacting with chlorophyll to produce chlorophyllin.[12] However, this tends to affect taste, texture and nutritional content, and is no longer common.[13] Baking soda is still used, though, in the traditional British mushy peas recipe for soaking the peas. It is also used in Asian and Latin American cuisine to tenderize meats. Baking soda may react with acids in food, including vitamin C (L-ascorbic acid). It is also used in breading, such as for fried foods, to enhance crispness and allow passages for steam to escape, so the breading is not blown off during cooking.

Baking powder[edit]
Baking powder, also sold for cooking, contains around 30% of bicarbonate, and various acidic ingredients which are activated by the addition of water, without the need for additional acids in the cooking medium.[14][15][16]Many forms of baking powder contain sodium bicarbonate combined with calcium acid phosphate, sodium aluminium phosphate, or cream of tartar.[17] Baking soda is alkaline; the acid used in baking powder avoids a metallic taste when the chemical change during baking creates sodium carbonate.
Pest control[edit]
Sodium bicarbonate can be an effective way of controlling fungal growth,[18] and in the United States is registered by the Environmental Protection Agency as a biopesticide.[19]
Alkalinity/pH increase[edit]
Sodium bicarbonate can be administered to pools, spas, and garden ponds to raise the total alkalinity. This will also raise the pH level and make maintaining proper pH easier. In the event that the pH is high, sodium bicarbonate should not be used to adjust the pH.[20]
Pyrotechnics[edit]
Sodium bicarbonate is one of the main components of the common 'black snake' firework. The effect is caused by the thermal decomposition, which produces carbon dioxide gas to produce a long snake-like ash as a combustion product of the other main component, sucrose.
Mild disinfectant[edit]
It has weak disinfectant properties,[21][22] and it may be an effective fungicide against some organisms.[23] Because baking soda will absorb musty smells, it has become a reliable method for used book sellers when making books less malodorous.[24]
Fire extinguisher[edit]
Sodium bicarbonate can be used to extinguish small grease or electrical fires by being thrown over the fire, as heating of sodium bicarbonate releases carbon dioxide.[25] However, it should not be applied to fires in deep fryers; the sudden release of gas may cause the grease to splatter.[25] Sodium bicarbonate is used in BC dry chemicalfire extinguishers as an alternative to the more corrosive diammonium phosphate in ABC extinguishers. The alkaline nature of sodium bicarbonate makes it the only dry chemical agent, besides Purple-K, that was used in large-scale fire suppression systems installed in commercial kitchens. Because it can act as an alkali, the agent has a mild saponification effect on hot grease, which forms a smothering, soapy foam.
Neutralization of acids and bases[edit]
Sodium bicarbonate is amphoteric, reacting with acids and bases. It reacts violently with acids, releasing CO2 gas as a reaction product. It is commonly used to neutralize unwanted acid solutions or acid spills in chemical laboratories.
Medical uses and health[edit]
Sodium bicarbonate mixed with water can be used as an antacid to treat acid indigestion and heartburn.[26] Its reaction with stomach acid produces salt, water, and carbon dioxide:
- NaHCO3 + HCl → NaCl + H2O + CO2(g)
A mixture of sodium bicarbonate and polyethylene glycol such as PegLyte,[27] dissolved in water and taken orally, is an effective gastrointestinal lavage preparation and laxative prior to gastrointestinal surgery, gastroscopy, etc.
Intravenous sodium bicarbonate in an aqueous solution is sometimes used for cases of acidosis, or when insufficient sodium or bicarbonate ions are in the blood.[28] In cases of respiratory acidosis, the infused bicarbonate ion drives the carbonic acid/bicarbonate buffer of plasma to the left, and thus raises the pH. For this reason, sodium bicarbonate is used in medically supervised cardiopulmonary resuscitation. Infusion of bicarbonate is indicated only when the blood pH is markedly low (< 7.1–7.0).[29]
HCO3− is used for treatment of hyperkalemia, as it will drive K+ back into cells during periods of acidosis.[30] Since sodium bicarbonate can cause alkalosis, it is sometimes used to treat aspirin overdoses. Aspirin requires an acidic environment for proper absorption, and the basic environment diminishes aspirin absorption in the case of an overdose.[31] Sodium bicarbonate has also been used in the treatment of tricyclic antidepressant overdose.[32] It can also be applied topically as a paste, with three parts baking soda to one part water, to relieve some kinds of insect bites and stings (as well as accompanying swelling).[33]
Some alternative practitioners, such as Tullio Simoncini, have promoted baking soda as a cancer cure, which the American Cancer Society has warned against due to both its unproven effectiveness and potential danger in use.[34]Edzard Ernst has called the promotion of sodium bicarbonate as a cancer cure 'one of the more sickening alternative cancer scams I have seen for a long time'.[35]
Sodium bicarbonate can be added to local anesthetics, to speed up the onset of their effects and make their injection less painful.[36] It is also a component of Moffett's solution, used in nasalsurgery.
As early as the 1920s, bicarbonate was found to cause increased bone strength in patients who were losing calcium in their urine. In 1968, diets producing too much acid were thought to put bones at risk.[37] Experiments by Anthony Sebastian of the University of California, San Francisco starting in the late 20th century found that the body was breaking down bones and muscles to release carbonates, phosphates, and ammonia, which neutralize acid. Adding bicarbonate to the diet (he chose to use the sodium-free saleratus, potassium bicarbonate) reduced loss of calcium in postmenopausal women, amounting to the equivalent of 'an arm-and-a-leg's worth' of bone if this continued for two decades.
Antacid (such as baking soda) solutions have been prepared and used by protesters to alleviate the effects of exposure to tear gas during protests.[38][not in citation given][39]
Similarly to its use in baking, sodium bicarbonate is used together with a mild acid such as tartaric acid as the excipient in effervescent tablets: when such a tablet is dropped in a glass of water, the carbonate leaves the reaction medium as carbon dioxide gas ( HCO3− + H+ → H2O + CO2↑ or, more precisely, HCO3− + H3O+ → 2 H2O + CO2↑ ) leaving the medication dissolved in the water together with the resulting salt (in this example, sodium tartrate).
Personal hygiene[edit]
Toothpaste containing sodium bicarbonate has in several studies been shown to have a better whitening[40][40][41][42] and plaque removal effect[43][44]than toothpastes without it.
Sodium bicarbonate is also used as an ingredient in some mouthwashes. It has anticaries and abrasive properties.[45] It works as a mechanical cleanser on the teeth and gums, neutralizes the production of acid in the mouth, and also acts as an antiseptic to help prevent infections.[46][47] Sodium bicarbonate in combination with other ingredients can be used to make a dry or wet deodorant.[48][49] Sodium bicarbonate may be used as a buffering agent, combined with table salt, when creating a solution for nasal irrigation.[50]
It is used in eye hygiene to treat blepharitis. This is done by addition of a teaspoon of sodium bicarbonate to cool water that was recently boiled, followed by gentle scrubbing of the eyelash base with a cotton swab dipped in the solution.[51]
Veterinary uses[edit]
Sodium bicarbonate is used as a cattle feed supplement, in particular as a buffering agent for the rumen.[52]
In sports[edit]
Small amounts of sodium bicarbonate have been shown to be useful as a supplement for athletes in speed-based events, such as middle-distance running, lasting about 1–7 minutes.[53][54] However, overdose is a serious risk because sodium bicarbonate is slightly toxic;[55] and gastrointestinal irritation is of particular concern.[54] Additionally, this practice causes an increase in dietary sodium.[56]
Cleaning agent[edit]
Sodium bicarbonate is used in a process for removing paint and corrosion called sodablasting; the process is particularly suitable for cleaning aluminium panels which can be distorted by other types of abrasives.
A manufacturer recommends a paste made from baking soda with minimal water as a gentle scouring powder,[25] and is useful in removing surface rust, as the rust forms a water-soluble compound when in a concentrated alkaline solution;[57] cold water should be used, as hot-water solutions can corrode steel.[58] Sodium bicarbonate attacks the thin protective oxide layer that forms on aluminium, making it unsuitable for cleaning this metal.[59] A solution in warm water will remove the tarnish from silver when the silver is in contact with a piece of aluminium foil.[59][60]Baking soda is commonly added to washing machines as a replacement for water softener and to remove odors from clothes. It is also effective in removing heavy tea and coffee stains from cups when diluted with warm water. Also, baking soda can be used as a multipurpose odor remover.[61]
During the Manhattan Project to develop the nuclear bomb in the early 1940s, the chemical toxicity of uranium was an issue. Uranium oxides were found to stick very well to cotton cloth, and did not wash out with soap or laundry detergent. However, the uranium would wash out with a 2% solution of sodium bicarbonate. Clothing can become contaminated with toxic dust of depleted uranium (DU), which is very dense, hence used for counterweights in a civilian context, and in armour-piercing projectiles. DU is not removed by normal laundering; washing with about 6 ounces (170 g) of baking soda in 2 gallons (7.5 l) of water will help to wash it out.[62]
Chemistry[edit]
Sodium bicarbonate is an amphoteric compound. Aqueous solutions are very mildly alkaline due to the formation of carbonic acid and hydroxide ion:
- HCO−
3 + H2O → H
2CO
3 + OH−
Sodium bicarbonate can be used as a wash to remove any acidic impurities from a 'crude' liquid, producing a purer sample. Reaction of sodium bicarbonate and an acid produces a salt and carbonic acid, which readily decomposes to carbon dioxide and water:
- NaHCO3 + HCl → NaCl + H2CO3
- H2CO3 → H2O + CO2(g)
Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide:
- NaHCO3 + CH3COOH → CH3COONa + H2O + CO2(g)
Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates:
- NaHCO3 + NaOH → Na2CO3 + H2O
Sodium bicarbonate reacts with carboxyl groups in proteins to give a brisk effervescence from the formation of CO
2. This reaction is used to test for the presence of carboxylic groups in protein.[citation needed]
2. This reaction is used to test for the presence of carboxylic groups in protein.[citation needed]
Thermal decomposition[edit]
Above 50 °C (122 °F), sodium bicarbonate gradually decomposes into sodium carbonate, water, and carbon dioxide. The conversion is fast at 200 °C (392 °F):[63]
- 2 NaHCO3 → Na2CO3 + H2O + CO2
Medicinal Uses For Baking Soda
Most bicarbonates undergo this dehydration reaction. Further heating converts the carbonate into the oxide (above 850 °C/1,560 °F):[63]
- Na2CO3 → Na2O + CO2
These conversions are relevant to the use of NaHCO3 as a fire-suppression agent ('BC powder') in some dry-powder fire extinguishers.
History[edit]
How Much Baking Soda Daily
In 1791, French chemist Nicolas Leblanc produced sodium carbonate, also known as soda ash. In 1846, two New York bakers, John Dwight and Austin Church, established the first factory in the United States to produce baking soda from sodium carbonate and carbon dioxide.[64]
Saleratus, potassium or sodium bicarbonate, is mentioned in the novel Captains Courageous by Rudyard Kipling as being used extensively in the 1800s in commercial fishing to prevent freshly caught fish from spoiling.[65]
Production[edit]
Sodium bicarbonate is produced industrially from sodium carbonate:[66]
- Na2CO3 + CO2 + H2O → 2 NaHCO3
It is produced on the scale of about 100,000 tonnes/year (as of 2001).[67] Commercial quantities of baking soda are also produced by a similar method: soda ash, mined in the form of the ore trona, is dissolved in water and treated with carbon dioxide. Sodium bicarbonate precipitates as a solid from this solution.
Regarding the Solvay process, sodium bicarbonate is an intermediate in the reaction of sodium chloride, ammonia, and carbon dioxide. The product however shows low purity (75%).
Although of no practical value, NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide:
- CO2 + NaOH → NaHCO3
Mining[edit]
Naturally occurring deposits of nahcolite (NaHCO3) are found in the Eocene-age (55.8–33.9 Mya) Green River Formation, Piceance Basin in Colorado. Nahcolite was deposited as beds during periods of high evaporation in the basin. It is commercially mined using common underground mining techniques such as bore, drum, and longwall mining in a fashion very similar to coal mining.
Limited amounts of product are further obtained by solution mining, pumping heated water through previously mined nahcolite beds and reconstituting the dissolved nahcolite above ground through a natural cooling crystallization process. Currently, only Genesis Alkali (formerly Tronox, formerly FMC) in the Green River Wyoming basin has successfully commercially solution mined the product.
In popular culture[edit]
Film[edit]
Sodium bicarbonate, as 'bicarbonate of soda', was a frequent source of punch lines for Groucho Marx in Marx brothers movies. In Duck Soup, Marx plays the leader of a nation at war. In one scene, he receives a message from the battlefield that his general is reporting a gas attack, and Groucho tells his aide: 'Tell him to take a teaspoonful of bicarbonate of soda and a half a glass of water.'[68] In A Night at the Opera, Groucho's character addresses the opening night crowd at an opera by saying of the lead tenor: 'Signor Lassparri comes from a very famous family. His mother was a well-known bass singer. His father was the first man to stuff spaghetti with bicarbonate of soda, thus causing and curing indigestion at the same time.'[69]
In the 2019 film Cold Pursuit, the villain chastises one of his henchmen for packing unhealthy snacks into his son's lunch: 'High-fructose corn syrup? Lecithin? Baking soda? The only thing not in those is rat poison!'

I don’t mean to sound seditious here, but I have a rebellious plan to combat the ills that many corporations are perpetrating in the name of fighting grime and germs. My main gripe is about the environmental pollutants from cleaning and personal care products that we wash down our drains and into our water systems, resulting in situations like the chemical triclosan (a pesticide added to many products as an antibacterial agent) being found in dolphins.
So the simple plan is to encourage everyone to use baking soda in any of these 51 applications. Besides showing kindness to aquatic life, we can also protect ourselves from the array of toxins in household cleaning products. Conventional cleansers can expose us to multiple chemicals linked to asthma, cancer and other documented health problems.
Baking soda also makes a perfect stand-in for many personal care products, which are adding their own twist to the toxic tangle of pollutants and personal health (mainly in the form of synthetic fragrance (and it’s almost all synthetic), sodium laurel sulfate, and parabens).
So exactly how does baking soda fit into my scheme to make the world a better place? Baking soda, aka sodium bicarbonate, helps regulate pH—keeping a substance neither too acidic nor too alkaline. When baking soda comes in contact with either an acidic or an alkaline substance, its natural effect is to neutralize that pH. Beyond that, baking soda has the ability to retard further changes in the pH balance, known as buffering. This dual capability of neutralizing and buffering allows baking soda to do things such as neutralize acidic odors (like in the refrigerator) as well as maintain neutral pH (like in your laundry water, which helps boost your detergent’s power). It’s a simple reaction, but one that has far-reaching effects for a number of cleaning and deodorizing tasks. And so without further ado, I’ll remove my scientist cap, put on my rebellious housekeeper’s cap, and get this folk-wisdom revolution rolling…
Personal Care Uses for Baking Soda
1. Make Toothpaste
A paste made from baking soda and a 3 percent hydrogen peroxide solution can be used as an alternative to commercial non-fluoride toothpastes. (Or here’s a formula for a minty version.) You can also just dip your toothbrush with toothpaste into baking soda for an extra boost.

49. Extinguish Fires
Baking soda can help in the initial handling of minor grease or electrical kitchen fires, because when baking soda is heated, it gives off carbon dioxide, which helps to smother the flames. For small cooking fires (frying pans, broilers, ovens, grills), turn off the gas or electricity if you can safely do so. Stand back and throw handfuls of baking soda at the base of the flame to help put out the fire–and call the Fire Department just to be safe. (And, you should have a fire extinguisher on hand anyway, here’s why.

Sodium bicarbonate, commonly known as baking soda, is a chemical compound that has a myriad of uses. It is widely used to treat numerous medical issues, including heartburn, indigestion, high potassium levels in the blood and high acid levels in the blood or urine, and in certain instances, it can be used to treat a drug overdose. As a topical paste, it can be used to relieve the symptoms accompanying an insect bite.
Individuals can purchase sodium bicarbonate over the counter, and it comes in several forms for medicinal use. It typically is available as tablets, capsules, granules, powder or a solution. These forms of the compound are taken orally. It also can be administered intravenously, and this form is available only by prescription.
The most common medicinal use for baking soda is as an antacid to reduce indigestion and heartburn. When using the compound for this purpose, individuals should take it an hour or two after a meal and with a glass of water. It reduces the amount of acid in the stomach, and individuals typically experience relief shortly after taking it.
Sodium bicarbonate also is sometimes used to treat hyperkalemia. This condition occurs when potassium levels are excessively high in the blood. Some symptoms of the illness are irregular heartbeat and nausea, but complications can occur, and hyperkalemia can be dangerous if not treated.
